mfd: twl-core: Constify struct regmap_config and reg_default array

2015-01-22T16:03:48Z

The regmap_config struct may be const because it is not modified by the driver and regmap_init() accepts pointer to const. Make array of struct reg_default const as well. Signed-off-by: Krzysztof Kozlowski Acked-by: Tony Lindgren Signed-off-by: Lee Jones

Merge tag 'ib-mfd-omap-3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd into omap-for-v3.16/pm

Immutable branch between MFD and ARM OMAP due for v3.16 merge-window.

mfd: twl-core: Fix idle mode signaling for omaps when booted with device tree

2014-04-23T14:31:05Z

I noticed a regression where the omap sys_clkreq signal will never trigger for omap3 when booted with device tree while it triggers when booted in legacy mode. This means voltage scaling does not do anything when booted with device tree. Turns out the reason is we fail to initialize the SmartReflex enable bit in twl4030 with the following error: twl: not initialized And that happens because we are wrongly tinkering with the twl4030 registers in arch/arm/mach-omap2/omap_twl.c before the driver is initialized. Looking at the the SmartReflex bit enable code in omap_twl.c, we need to always set it. So let's fix the issue by always enabling the twl4030 SmartReflex bit in the drivers/mfd/twl-core.c probe, and drop the related code in omap_twl.c. Note that we still have some twl4030 tinkering left in omap_twl.c for the twl6030 case, but that's a different patch. Signed-off-by: Tony Lindgren Signed-off-by: Lee Jones

mfd: twl-core: Fix accessibility of some twl4030 audio registers

2014-03-19T08:58:43Z

There are some unused registers in twl4030 at I2C address 0x49 and function twl4030_49_nop_reg() is used to check accessibility of that registers. These registers are written in decimal format but the values are correct in hexadecimal format. (It can be checked few lines above the patched code - these registers are marked as unused there.) As a consequence three registers of audio submodule are treated as inaccessible (preamplifier carkit right and both handsfree registers).

Merge tag 'ib-asoc-3.14.2' into for-mfd-next

mfd: twl-core: Fix passing of platform data in the device tree case

2014-01-21T08:13:38Z

Since we still need to rely on a mix of device tree initialized drivers and legacy platform data initialize drivers, let's fix the passing of platform data to twl4030-gpio. As the twl4030 GPIO is initialized by twl-core.c, we need to register the auxdata for twl4030 GPIO in twl-core.c. Signed-off-by: Tony Lindgren Signed-off-by: Lee Jones

mfd: twl-core: Clean up module by removing twl603x pdata handling

2014-01-21T08:13:38Z

Since currently nobody uses TWL603x platform data and all new users will supply it through device tree, handling of these data within twl-core will never be used, so remove it. Signed-off-by: Ruslan Ruslichenko Signed-off-by: Lee Jones

mfd: twl-core: Enable regcache for audio registers

2014-01-08T11:37:52Z

Enable regmap's regcache for the audio registers: i2c address 0x49, register range 0x01 - 0x49 Mark all other registers as volatile to avoid any side effect for the non audio functions behind 0x49 i2c address. Signed-off-by: Peter Ujfalusi Acked-by: Mark Brown Signed-off-by: Lee Jones

mfd: twl-core: API to set the regcache bypass for a given regmap in twl

2014-01-08T11:37:39Z

If the regcache is enabled on the regmap module drivers might need to access to HW register(s) in certain cases in cache bypass mode. As an example of this is the audio block's ANAMICL register. In normal operation the content can be cached but during initialization one bit from the register need to be monitored. With the twl_set_regcache_bypass() the client driver can switch regcache bypass on and off when it is needed so we can utilize the regcache for more registers.

mfd: twl-core: Simplify IO wrapper functions by moving common code out

2014-01-08T11:36:59Z

The new twl_get_regmap() function will return a pointer to the regmap needed for the given module. Since both read and write function were using the same code to do the lookup we can reuse this in both places to simplify the code.
