2010-12-07OMAP2+: GPIO: device registrationVaradarajan, Charulatha
Use omap_device_build() API to do platform_device_register of GPIO devices. For OMAP2+ chips, the device specific data defined in the centralized hwmod database will be used. gpio_init needs to be done before machine_init functions access gpio APIs. Hence gpio_init is made as a postcore_initcall.

2010-12-07OMAP: GPIO: prepare for platform driverVaradarajan, Charulatha
Prepare for implementing GPIO as a platform driver. Modifies omap_gpio_init() to make use of omap_gpio_chip_init() and omap_gpio_mod_init(). omap_gpio_mod_init() does the module init by clearing the status register and initializing the GPIO control register. omap_gpio_chip_init() initializes the chip request, free, get, set and other function pointers and sets the gpio irq handler. This is only to reorganize the code so that the "omap gpio platform driver implementation patch" looks cleaner and better to review.

Commit 4d17aeb1c5b2375769446d13012a98e6d265ec13 ("OMAP: I2C: split device registration and convert OMAP2+ to omap_device") broke I2C on OMAP1. The following messages appear at boot: i2c_omap i2c_omap.1: failure requesting irq 0 i2c_omap: probe of i2c_omap.1 failed with error -22 Investigation revealed that a chunk of code is missing from the original plat-omap/i2c.c file which configured the IRQ and base address for the I2C block on OMAP1. Upon adding this back, the OMAP1 I2C block seems to initialize correctly. Thanks to Cory Maccarrone <darkstar6262@gmail.com> for reporting the bug, and apologies for the breakage.

2010-11-24OMAP2+: PM/serial: hold console semaphore while OMAP UARTs are disabledPaul Walmsley
The console semaphore must be held while the OMAP UART devices are disabled, lest a console write cause an ARM abort (and a kernel crash) when the underlying console device is inaccessible. These crashes only occur when the console is on one of the OMAP internal serial ports. While this problem has been latent in the PM idle loop for some time, the crash was not triggerable with an unmodified kernel until commit 6f251e9db1093c187addc309b5f2f7fe3efd2995 ("OMAP: UART: omap_device conversions, remove implicit 8520 assumptions"). After this patch, a console write often occurs after the console UART has been disabled in the idle loop, crashing the system. Several users have encountered this bug: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg38396.html http://www.mail-archive.com/linux-omap@vger.kernel.org/msg36602.html The same commit also introduced new code that disabled the UARTs during init, in omap_serial_init_port(). The kernel will also crash in this code when earlyconsole and extra debugging is enabled: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg36411.html The minimal fix for the -rc series is to hold the console semaphore while the OMAP UARTs are disabled. This is a somewhat overbroad fix, since the console may not be located on an OMAP UART, as is the case with the GPMC UART on Zoom3. While it is technically possible to determine which devices the console or earlyconsole is actually running on, it is not a trivial problem to solve, and the code to do so is not really appropriate for the -rc series. The right long-term fix is to ensure that no code outside of the OMAP serial driver can disable an OMAP UART. As I understand it, code to implement this is under development by TI. This patch is a collaboration between Paul Walmsley <paul@pwsan.com> and Tony Lindgren <tony@atomide.com>.

Add additional check to omap_uart_resume_idle() so that only enabled (specifically, idle-enabled) UARTs are allowed to resume. This matches the existing check in prepare idle.

2010-11-24ARM: 6482/2: Fix find_next_zero_bit and related assemblyJames Jones
The find_next_bit, find_first_bit, find_next_zero_bit and find_first_zero_bit functions were not properly clamping to the maxbit argument at the bit level. They were instead only checking maxbit at the byte level. To fix this, add a compare and a conditional move instruction to the end of the common bit-within-the- byte code used by all the functions and be sure not to clobber the maxbit argument before it is used.
