2023-05-15clk: RK808: Reduce 'struct rk808' usageSebastian Reichel1-18/+16
Reduce usage of 'struct rk808' (driver data of the parent MFD), so that only the chip variant field is still being accessed directly. This allows restructuring the MFD driver to support SPI based PMICs.

2016-09-09clk: rk808: Pass the right pointer as the get_hw contextTomeu Vizoso1-1/+1
Right now we are passing a pointer to a pointer to the structure that will be used to fetch the clk hw, which gets casted later to a pointer to the structure, thus getting garbage in the hw structs.

2016-08-25clk: rk808: Migrate to clk_hw based OF and registration APIsStephen Boyd1-22/+22
Now that we have clk_hw based provider APIs to register clks, we can get rid of struct clk pointers while registering clks in these drivers, allowing us to move closer to a clear split of consumer and provider clk APIs.

2015-07-20clk: rk808: Remove clk.h includeStephen Boyd1-1/+0
Clock provider drivers generally shouldn't include clk.h because it's the consumer API. Remove the include here because this is a provider driver. Cc: Chris Zhong <zyw@rock-chips.com> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
2014-10-14clk: RK808: add clkout driver for RK808Chris Zhong1-0/+170
This is the initial version of the RK808 PMIC. This is a power management IC for multimedia products. It provides regulators that are able to supply power to processor cores and other components. The chip provides other modules including RTC, Clockout.
