Subject[PATCH 11/11] staging: ti dspbridge: enable driver building
Date
From: Omar Ramirez Luna <omar.ramirez@ti.com>

Add Kconfig + Makefile for TI's DSP Bridge driver
and expose it to the staging menu.

For now, have tidspbridge depend on ARCH_OMAP3.
That dependency should be relaxed as soon as required cleanups are applied.

+menuconfig TIDSPBRIDGE
+ tristate "DSP Bridge driver"
+ depends on ARCH_OMAP3
+ select OMAP_MBOX_FWK
+ help
+ DSP/BIOS Bridge is designed for platforms that contain a GPP and
+ one or more attached DSPs. The GPP is considered the master or
+ "host" processor, and the attached DSPs are processing resources
+ that can be utilized by applications and drivers running on the GPP.
+
+ This driver depends on OMAP Mailbox (OMAP_MBOX_FWK).
+
+config BRIDGE_DVFS
+ bool "Enable Bridge Dynamic Voltage and Frequency Scaling (DVFS)"
+ depends on TIDSPBRIDGE && OMAP_PM_SRF && CPU_FREQ
+ default n
+ help
+ DVFS allows DSP Bridge to initiate the operating point change to
+ scale the chip voltage and frequency in order to match the
+ performance and power consumption to the current processing
+ requirements.
+
+config BRIDGE_MEMPOOL_SIZE
+ hex "Physical memory pool size (Byte)"
+ depends on TIDSPBRIDGE
+ default 0x600000
+ help
+ Allocate specified size of memory at booting time to avoid allocation
+ failure under heavy memory fragmentation after some use time.
+
+config BRIDGE_DEBUG
+ bool "DSP Bridge Debug Support"
+ depends on TIDSPBRIDGE
+ help
+ Say Y to enable Bridge debugging capabilities
+
+config BRIDGE_RECOVERY
+ bool "DSP Recovery Support"
+ depends on TIDSPBRIDGE
+ help
+ In case of DSP fatal error, BRIDGE driver will try to
+ recover itself.
+
+config BRIDGE_CACHE_LINE_CHECK
+ bool "Check buffers to be 128 byte aligned"
+ depends on TIDSPBRIDGE
+ default n
+ help
+ When the DSP processes data, the DSP cache controller loads 128-Byte
+ chunks (lines) from SDRAM and writes the data back in 128-Byte chunks.
+ If a DMM buffer does not start and end on a 128-Byte boundary, the data
+ preceding the start address (SA) from the 128-Byte boundary to the SA
+ and the data at addresses trailing the end address (EA) from the EA to
+ the next 128-Byte boundary will be loaded and written back as well.
+ This can lead to heap corruption. Say Y, to enforce the check for 128
+ byte alignment, buffers failing this check will be rejected.
+
+config BRIDGE_WDT3
+ bool "Enable WDT3 interruptions"
+ depends on TIDSPBRIDGE
+ default n
+ help
+ WTD3 is managed by DSP and once it is enabled, DSP side bridge is in
+ charge of refreshing the timer before overflow, if the DSP hangs MPU
+ will caught the interrupt and try to recover DSP.
+
+config WDT_TIMEOUT
+ int "DSP watchdog timer timeout (in secs)"
+ depends on BRIDGE_WDT3
+ default 5
+ help
+ Watchdog timer timeout value, after that time if the watchdog timer
+ counter is not reset the wdt overflow interrupt will be triggered
+
+comment "Bridge Notifications"
+ depends on TIDSPBRIDGE
+
+config BRIDGE_NTFY_PWRERR
+ bool "Notify DSP Power Error"
+ depends on TIDSPBRIDGE
+ help
+ Enable notifications to registered clients on the event of power errror
+ trying to suspend bridge driver. Say Y, to signal this event as a fatal
+ error, this will require a bridge restart to recover.
