2013-01-03ARM: OMAP1: fix USB configuration use-after-releaseAaro Koskinen
All boards, except Amstrad E3, mark USB config with __initdata. As a result, when you compile USB into modules, they will try to refer already released platform data and the behaviour is undefined. For example on Nokia 770, I get the following kernel panic when modprobing ohci-hcd: [ 3.462158] Unable to handle kernel paging request at virtual address e7fddef0 [ 3.477050] pgd = c3434000 [ 3.487365] [e7fddef0] *pgd=00000000 [ 3.498535] Internal error: Oops: 80000005 [#1] ARM [ 3.510955] Modules linked in: ohci_hcd(+) [ 3.522705] CPU: 0 Not tainted (3.7.0-770_tiny+ #5) [ 3.535552] PC is at 0xe7fddef0 [ 3.546508] LR is at ohci_omap_init+0x5c/0x144 [ohci_hcd] [ 3.560272] pc : [<e7fddef0>] lr : [<bf003140>] psr: a0000013 [ 3.560272] sp : c344bdb0 ip : c344bce0 fp : c344bdcc [ 3.589782] r10: 00000001 r9 : 00000000 r8 : 00000000 [ 3.604553] r7 : 00000026 r6 : 000000de r5 : c0227300 r4 : c342d620 [ 3.621032] r3 : e7fddef0 r2 : c048b880 r1 : 00000000 r0 : 0000000a [ 3.637786] Flags: NzCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment user [ 3.655822] Control: 0005317f Table: 13434000 DAC: 00000015 [ 3.672790] Process modprobe (pid: 425, stack limit = 0xc344a1b8) [ 3.690643] Stack: (0xc344bdb0 to 0xc344c000) [ 3.707031] bda0: bf0030e4 c342d620 00000000 c049e62c [ 3.727905] bdc0: c344be04 c344bdd0 c0150ff0 bf0030f4 bf001b88 00000000 c048a4ac c345b020 [ 3.748870] bde0: c342d620 00000000 c048a468 bf003968 00000001 bf006000 c344be34 c344be08 [ 3.769836] be00: bf001bf0 c0150e48 00000000 c344be18 c00b9bfc c048a478 c048a4ac bf0037f8 [ 3.790985] be20: c012ca04 c000e024 c344be44 c344be38 c012d968 bf001a84 c344be64 c344be48 [ 3.812164] be40: c012c8ac c012d95c 00000000 c048a478 c048a4ac bf0037f8 c344be84 c344be68 [ 3.833740] be60: c012ca74 c012c80c 20000013 00000000 c344be88 bf0037f8 c344beac c344be88 [ 3.855468] be80: c012b038 c012ca14 c38093cc c383ee10 bf0037f8 c35be5a0 c049d5e8 00000000 [ 3.877166] bea0: c344bebc c344beb0 c012c40c c012aff4 c344beec c344bec0 c012bfc0 c012c3fc [ 3.898834] bec0: bf00378c 00000000 c344beec bf0037f8 00067f39 00000000 00005c44 c000e024 [ 3.920837] bee0: c344bf14 c344bef0 c012cd54 c012befc c04ce080 00067f39 00000000 00005c44 [ 3.943023] bf00: c000e024 bf006000 c344bf24 c344bf18 c012db14 c012ccc0 c344bf3c c344bf28 [ 3.965423] bf20: bf00604c c012dad8 c344a000 bf003834 c344bf7c c344bf40 c00087ac bf006010 [ 3.987976] bf40: 0000000f bf003834 00067f39 00000000 00005c44 bf003834 00067f39 00000000 [ 4.010711] bf60: 00005c44 c000e024 c344a000 00000000 c344bfa4 c344bf80 c004c35c c0008720 [ 4.033569] bf80: c344bfac c344bf90 01422192 01427ea0 00000000 00000080 00000000 c344bfa8 [ 4.056518] bfa0: c000dec0 c004c2f0 01422192 01427ea0 01427ea0 00005c44 00067f39 00000000 [ 4.079406] bfc0: 01422192 01427ea0 00000000 00000080 b6e11008 014221aa be941fcc b6e1e008 [ 4.102569] bfe0: b6ef6300 be941758 0000e93c b6ef6310 60000010 01427ea0 00000000 00000000 [ 4.125946] Backtrace: [ 4.143463] [<bf0030e4>] (ohci_omap_init+0x0/0x144 [ohci_hcd]) from [<c0150ff0>] (usb_add_hcd+0x1b8/0x61c) [ 4.183898] r6:c049e62c r5:00000000 r4:c342d620 r3:bf0030e4 [ 4.205596] [<c0150e38>] (usb_add_hcd+0x0/0x61c) from [<bf001bf0>] (ohci_hcd_omap_drv_probe+0x17c/0x224 [ohci_hcd]) [ 4.248138] [<bf001a74>] (ohci_hcd_omap_drv_probe+0x0/0x224 [ohci_hcd]) from [<c012d968>] (platform_drv_probe+0x1c/0x20) [ 4.292144] r8:c000e024 r7:c012ca04 r6:bf0037f8 r5:c048a4ac r4:c048a478 [ 4.316192] [<c012d94c>] (platform_drv_probe+0x0/0x20) from [<c012c8ac>] (driver_probe_device+0xb0/0x208) [ 4.360168] [<c012c7fc>] (driver_probe_device+0x0/0x208) from [<c012ca74>] (__driver_attach+0x70/0x94) [ 4.405548] r6:bf0037f8 r5:c048a4ac r4:c048a478 r3:00000000 [ 4.429809] [<c012ca04>] (__driver_attach+0x0/0x94) from [<c012b038>] (bus_for_each_dev+0x54/0x90) [ 4.475708] r6:bf0037f8 r5:c344be88 r4:00000000 r3:20000013 [ 4.500366] [<c012afe4>] (bus_for_each_dev+0x0/0x90) from [<c012c40c>] (driver_attach+0x20/0x28) [ 4.528442] r7:00000000 r6:c049d5e8 r5:c35be5a0 r4:bf0037f8 [ 4.553466] [<c012c3ec>] (driver_attach+0x0/0x28) from [<c012bfc0>] (bus_add_driver+0xd4/0x228) [ 4.581878] [<c012beec>] (bus_add_driver+0x0/0x228) from [<c012cd54>] (driver_register+0xa4/0x134) [ 4.629730] r8:c000e024 r7:00005c44 r6:00000000 r5:00067f39 r4:bf0037f8 [ 4.656738] [<c012ccb0>] (driver_register+0x0/0x134) from [<c012db14>] (platform_driver_register+0x4c/0x60) [ 4.706542] [<c012dac8>] (platform_driver_register+0x0/0x60) from [<bf00604c>] (ohci_hcd_mod_init+0x4c/0x8c [ohci_hcd]) [ 4.757843] [<bf006000>] (ohci_hcd_mod_init+0x0/0x8c [ohci_hcd]) from [<c00087ac>] (do_one_initcall+0x9c/0x174) [ 4.808990] r4:bf003834 r3:c344a000 [ 4.832641] [<c0008710>] (do_one_initcall+0x0/0x174) from [<c004c35c>] (sys_init_module+0x7c/0x194) [ 4.881530] [<c004c2e0>] (sys_init_module+0x0/0x194) from [<c000dec0>] (ret_fast_syscall+0x0/0x2c) [ 4.930664] r7:00000080 r6:00000000 r5:01427ea0 r4:01422192 [ 4.956481] Code: bad PC value [ 4.978729] ---[ end trace 58280240f08342c4 ]--- [ 5.002258] Kernel panic - not syncing: Fatal exception Fix this by taking a copy of the data.

2012-12-24ARM: delete struct sys_timerStephen Warren
Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

2012-10-04ASoC: ams-delta: Convert to use snd_soc_register_card()Janusz Krzysztofik
The old method of registering with the ASoC core by creating a "soc-audio" platform device no longer works for Amstrad Delta sound card after recent changes to drvdata handling (commit 0998d0631001288a5974afc0b2a5f568bcdecb4d, 'device-core: Ensure drvdata = NULL when no driver is bound'. Use snd_soc_register_card() method instead, as suggested by the ASoC core generated warning message, and move both the card and codec platform device registration to the arch board file where those belong.

Once done, remove the no longer used AMS_DELTA_LATCH2_MODEM_NRESET symbol from the board header file and a call to the regulator_toggle() helper function from the old API wrapper found in the board file. While being at it, simplify the way the modem .pm callback handles the regulator and drop that helper function and its related consumer setup completely.

After the CX20442 codec driver already takes care of enabling the codec power for itself (commit f75a8ff67d161b5166a2c2360bb2ffaefd5eb853, "ASoC: cx20442: add bias control over a platform provided regulator"), but before dropping the old bias control method from the Amstrad Delta ASoC sound card file, which in fact keeps the modem power always on, even on the ASoC device close for now, extend the modem setup with a power management callback which toggles the regulator up to the modem's needs, reusing the previously set up regulator consumer for this. Also, drop the MODEM_NRESET pin setup from the modem initialization procedure, as this operation was already ineffective since patch 1/3, and not needed because the regulator is set up as initially enabled. Depends on patch 1/3 "ARM: OMAP1: ams-delta: set up regulator over modem reset GPIO pin" to apply cleanly.

The Amstrad Delta on-board latch2 bit named MODEM_NRESET, now available as a GPIO pin AMS_DELTA_GPIO_PIN_NMODEM_RESET, is used to power up/down (bring into/out of a reset state) two distinct on-board devices simultaneously: the modem, and the voice codec. As a consequence, that bit is, or can be, manipulated concurrently by two drivers, or their platform provided hooks. Instead of updating those drivers to use the gpiolib API as a new method of controlling the MODEM_NRESET pin state, like it was done to other drivers accessing latch2 pins, and still being vulnerable to potential concurrency conflicts, or trying to solve that sharing issue with a custom piece of code, set up a fixed regulator device on top of that GPIO pin, with the intention of updating both drivers to manipulate that regulator, not the GPIO pin directly. Before the ASoC driver is updated and the modem platform data expanded with a power management callback for switching its power, the ams_delta_latch_write() function, which still provides the old API for accessing latch2 functionality from not updated drivers, is modified to toggle the regulator instead of the MODEM_NRESET GPIO pin. A helper function provided for balancing the regulator enable/disable operations, together with the consumer data needed for tracking the regulator state, will be removed once the drivers are updated.

The main purpose of this patch is to fix several section mismatch warnings from the board file and a few board specific drivers, introduced with recent Amstrad Delta patch series, some of them rising up only when building with CONFIG_MODULES not set.

2012-02-23OMAP1: pass LCD config with omapfb_set_lcd_config()Tomi Valkeinen
LCD config for old omapfb driver is passed with OMAP_TAG_LCD from board files or from the bootloader. In an effort to remove OMAP_TAG_LCD, this patch adds omapfb_set_lcd_config() function that the board files can call to set the LCD config. This has the drawback that configuration can no longer come from the bootloader. Of the boards supported by the kernel, this should only affect N770 which depends on the data from the bootloader. This patch adds an LCD config for N770 to its board files, but that is most probably broken. Fixing this would need information about the HW setup in N770 boards.

Don't use Amstrad Delta custom I/O functions once GPIO interface is available for the underlying hardware. While requesting and initializing GPIO pins used, also take care of one extra pin KEYBRD_DATAOUT which, even if not used by the driver, belongs to the device and affects its functioning. Once done, move the driver initialization back to the device_initcall level, reverting the temporary chane introduced with patch 1/7 "ARM: OMAP1: ams-delta: register latch dependent devices later". That change is no longer required once the driver takes care of registering used GPIO pins, and it's better to initialize the device before others using the latch2 based GPIO pins, otherwise a garbage is reported on boot, perhaps due to random data already captured by the FIQ handler while the keyboard related latch bits are written with random values during initialization of those other latch2 dependent devices.

2011-12-22ARM: OMAP1: ams-delta: convert latches to basic_mmio_gpioJanusz Krzysztofik
Once ready, ams-delta specific device drivers currently calling custom ams_delta_latch[12]_write() functions can be updated to call generic gpio_set_value() instead, which will make them less platform dependent. Even more, some custom ams-delta only drivers can perhaps be dropped from the tree after converting selected ams-delta platform devices to follow generic GPIO based device models. The latch_gpios[] table is initially filled with all latch1 and latch2 GPIO pins in order to register and initialize them from the board file until those are handled by respective existing device drivers (leds, nand, lcd, serio, asoc, serial). That table will get almost empty after the transision process is completed, holding only pins not used by any drivers / connected to unused devices, in order to initialize them from the board file for power saving purposes. The new ams_delta_latch_write() function is a unified replacement for those removed ams_delta_latch[12]_write(), and serves as a temporary wrapper over gpio_set_value(), providing the old API for those not yet updated device drivers, and will be removed after all custom drivers are converted or replaced.

2011-12-21ARM: OMAP1: ams-delta: register latch dependent devices laterJanusz Krzysztofik
In preparation to converting Amstrad Delta on-board latches to basic_mmio_gpio devices, registration of platform devices which depend on latches and will require initialization of their GPIO pins first, should be moved out of .machine_init down to late_initcall level, as the gpio-generic driver is not available until device_initcall time. The latch reset operation, which will be replaced with GPIO initialization, must also be moved to late_initcall for the same reason. Since there was already another, separate arch_initcall function for setting up one of those latch dependent devices, the on-board modem device, reuse that function, i.e., rename it to a name that matches the new purpose, extend with other device setup relocated from .machine_init, and move down to the late_initcall level. While being at it, add missing gpio_free() in case the modem platform device registration fails. Thanks to Tony Lindgren <tony@atomide.com> who suggested this approach instead of shifting up the gpio-generic driver initialization. In addition, defer registration of the Amstrad Delta ASoC and serio devices, done from their device driver files, until late_initcall time, as those drivers will depend on their GPIO pins already requested from the board late_init() function until updated to register their GPIO pins themselves.
