2010-05-06davinci: edma: fix coding style issue related to usage of bracesSekhar Nori
In the edma driver, there are couple of instances where braces are used for a single statement 'if' construct. There are other instances where 'else' part of the if-else construct does not use braces even if the 'if' part is a multi-line statement. This patch fixes both.

2010-05-06davinci: edma: use a more intuitive name for edma_infoSekhar Nori
'edma_info' structure inside the edma driver represents a single instance of edma channel controller. Call it 'edma_cc' instead. This also avoids readers confusing it with an instance of edma_soc_info structre which carries the platform data for a single channel controller instance.

2010-05-06Davinci: serial - conditional reset via pwremuCyril Chemparathy
With this patch, AR7 type uart ports are not reset via pwremu registers. This allows davinci_serial_init() reuse on tnetv107x soc. Signed-off-by: Cyril Chemparathy <cyril@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
2010-05-06Davinci: serial - use ioremap()Cyril Chemparathy
This patch implements davinci serial cleanups towards having this code reusable on tnetv107x. The change reuses the platform data membase field to hold the remapped space. By disabling the UPF_IOREMAP flag in the platform data, we prevent the 8250 driver from repeating the ioremap.

2010-05-06Davinci: serial - remove unnecessary defineCyril Chemparathy
The uart pdata array is already terminated by a zero flag field. This patch reuses this terminator and eliminates DAVINCI_MAX_NR_UARTS definition. This way, future platforms can have different number of uarts initialized via davinci_serial_init().

2010-05-06Davinci: watchdog reset separation across socsCyril Chemparathy
The earlier watchdog reset mechanism had a couple of limitations. First, it embedded a reference to "davinci_wdt_device" inside common code. This forced all derived platforms (da8xx and tnetv107x) to define such a device. This also would have caused problems in including multiple socs in a single build due to symbol redefinition. With this patch, davinci_watchdog_reset() now takes the platform device as an argument. The davinci_soc_info struct has been extended to include a reset function and a watchdog platform_device. arch_reset() then uses these elements to reset the system in a SoC specific fashion.

2010-05-06Davinci: eliminate pinmux offset verbosityCyril Chemparathy
Pinmux registers are sequential, and do not need to be enumerated out as they currently are. This reduces code volume and keeps things simple. If some future SoC comes up with a discontiguous register map, PINMUX() can then be expanded with local token pasting.

2010-05-06Davinci: gpio - fine grained lockingCyril Chemparathy

2010-05-06Davinci: gpio - controller type supportCyril Chemparathy
This patch allows for gpio controllers that deviate from those found on traditional davinci socs. davinci_soc_info has an added field to indicate the soc-specific gpio controller type. The gpio initialization code then bails out if necessary. More elements (tnetv107x) to be added later into enum davinci_gpio_type.

2010-05-06Davinci: gpio - register layout invariant inlinesCyril Chemparathy
This patch renders the inlined gpio accessors in gpio.h independent of the underlying controller's register layout. This is done by including three new fields in davinci_gpio_controller to hold the addresses of the set, clear, and in data registers. Other changes: 1. davinci_gpio_regs structure definition moved to gpio.c. This structure is no longer common across all davinci socs (davinci_gpio_controller is). 2. controller base address calculation code (gpio2controller()) moved to gpio.c as this was no longer necessary for the inline implementation. 3. modified inline range checks to use davinci_soc_info.gpio_num instead of DAVINCI_N_GPIO.

2010-05-06Davinci: gpio - structs and functions renamedCyril Chemparathy
Renamed gpio types to something more sensible: struct gpio_controller --> struct davinci_gpio_regs struct davinci_gpio --> struct davinci_gpio_controller gpio2controller() --> gpio2regs() irq2controller() --> irq2regs() This change also moves davinci_gpio_controller definition to gpio.h. Eventually, the gpio registers structure will be moved to gpio.c and no longer a common cross-soc definition.

2010-05-06DaVinci: move IDE platform device to its proper placeSergei Shtylyov
The IDE platform device is registered in three different places (2 board files for DM644x and in dm646x.c for DM646x) while both the IDE base address and the IDE IRQ are the same for both SoCs -- therefore, the proper place for the IDE platform seems to be in devices.c.

2010-05-06DaVinci: move AEMIF #define's to the proper headersSergei Shtylyov
Currently each DaVinci board file #define's its own version of the EMIFA base addresses (all named DAVINCI_ASYNC_EMIF_*_BASE), which leads to duplication. Move these #define's to the SoC specific headers, changing their prefixes from 'DAVINCI' to the 'DM355', 'DM644X', and 'DM646X' since all these base addresses are SoC specific... And while at it, rename DM646X_ASYNC_EMIF_DATA_CE0_BASE to DM646X_ASYNC_EMIF_CS2_SPACE_BASE in order to match the DM646x datasheet.

2010-05-06Davinci: support LPSC SwRstDisable stateCyril Chemparathy
The current clock control code always gates the clock (PSC state Disable = 2) on clk_disable(). Some on-chip peripherals (e.g. LCD controller on TNETV107X) need to be put into SwRstDisable = 0 on clock disable, to maintain hardware sanity. This patch extends the davinci_psc_config() arguments to pass in the desired module state instead of a boolean enable/disable. Further, clk_disable() now checks for the PSC_SWRSTDISABLE clk flag before selecting the target state.

2010-05-06Davinci: cpintc host map configurationCyril Chemparathy
Host map configuration instructs the interrupt controller to route interrupt channels to FIQ or IRQ lines. Currently, DA8xx family of devices leave these registers at their reset-default values. TNETV107X however does not have sane reset defaults, and therefore this architecture needs to reconfigure the host-map such that channels 0 and 1 go to FIQ, and the remaining channels raise IRQs. This patch adds an optional host map argument to cp_intc_init() for this. Signed-off-by: Cyril Chemparathy <cyril@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

2010-05-06davinci: edma: clear interrupt status for interrupt enabled channels onlyAnuj Aggarwal
Currently, the ISR in the EDMA driver clears the pending interrupt for all channels without regard to whether that channel has a registered callback or not. This causes problems for devices like DM355/DM365 where the multimedia accelerator uses EDMA by polling on the interrupt pending bits of some of the EDMA channels. Since these channels are actually allocated through the Linux EDMA driver (by an out-of-kernel module), the same shadow region is used by Linux and accelerator. There a race between the Linux ISR and the polling code running on the accelerator on the IPR (interrupt pending register). This patch fixes the issue by making the ISR clear the interrupts only for those channels which have interrupt enabled. The channels which are allocated for the purpose of being polled on by the accelerator will not have a callback function provided and so will not have IER (interrupt enable register) bits set. Tested on DM365 and OMAP-L137/L138 with audio and MMC/SD (as EDMA users).
