The upcoming TWL6030 is companion chip for OMAP4 like the current TWL4030
for OMAP3. The common modules like RTC, Regulator creates opportunity
to re-use the most of the code from twl4030.
Summary of Major difference between Triton and Phoenix chips are:
-GPIO, Keypad is not present in Phoenix
-I2C Chips addresses of modules like RTC, BCI, ADC, USB, PMC Master/Slave
have changed. Base address of these module register is also changed.
-PIH and SIH, module interrupt status registers will be replaced by PIH
(INT_STS_A, INT_STS_B and INT_STS_C) and module interrupt status registers
-MADC to GPADC in Phoenix, 17 channels supported
GPADC in Phoenix supports Realtime, Asynchronous SW request.
-RTC register offsets have changed. Addition/removal of LDO/SMPS Voltage
Regulators
These patches are generated against mainline 2.6.31-rc1 and validated on OMAP
3430 SDP for RTC driver and regulator drivers.
[PATCH 1/4] ARM: OMAP: Rename twl4030* driver files to enable re-use
[PATCH 2/4] ARM: OMAP: Rename all twl4030_i2c*.
[PATCH 3/4] ARM: OMAP: Rename twl4030_ in rtc-twl.c to make it generic twl rtc
[PATCH 4/4] Rename twl4030_ to twl_ in twl-regulator.c to make it generic twl reg
Below files needs updates/investigation for the possible re-use:
drivers/gpio/twl4030-gpio.c
drivers/usb/otg/twl4030-usb.c
drivers/input/misc/twl4030-pwrbutton.c
arch/arm/mach-omap2/board-rx51-peripherals.c
arch/arm/mach-omap2/board-omap3evm.c
Please provide your feedback on this patch series.
Thanks !!
