2017-02-13mfd: sun6i-prcm: Add codec analog controls sub-device for Allwinner A23Chen-Yu Tsai
The PRCM block on the A23 contains a message box like interface to the registers for the analog path controls of the internal codec. Add a sub-device for it.

2016-10-04mfd: sun6i-prcm: Make it explicitly non-modularPaul Gortmaker
The Kconfig currently controlling compilation of this code is: drivers/mfd/Kconfig:config MFD_SUN6I_PRCM drivers/mfd/Kconfig: bool "Allwinner A31 PRCM controller" ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modularity so that when reading the driver there is no doubt it is builtin-only. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.

2014-10-20mfd: drop owner assignment from platform_driversWolfram Sang
A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
2014-07-21mfd: sun6i-prcm: Add support for Allwinner A23 PRCMChen-Yu Tsai
The Allwinner A23 SoC has a PRCM unit like the previous A31 SoC. The differences are the AR100 clock can no longer be modified, the APB0 clock has different divisors, and some clock gates are gone. This patch adds a compatible with a modified subdevice list for the A23.

2014-06-03mfd: Add support for sun6i PRCM (Power/Reset/Clock Management) unitBoris BREZILLON
The PRCM (Power/Reset/Clock Management) block exposes several subdevices in different subsystems (clk, reset ...) Add basic support for the PRCM unit with clk (AR100, AHB0, and APB0 clks) and reset controller subdevices. Other subdevices might be added later (if needed).
