| * | | | | | | | | | | | | | | | | | Davinci: serial - conditional reset via pwremuCyril Chemparathy2010-05-06

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>

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.

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().

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.

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.

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>

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).
