Use devm_platform_ioremap_resource() to simplify code. Signed-off-by: Yangtao Li <frank.li@vivo.com> Link: https://lore.kernel.org/r/20230705065313.67043-7-frank.li@vivo.com Signed-off-by: Stephen Boyd <sboyd@kernel.org>
2023-07-19clk: Explicitly include correct DT includesRob Herring1-1/+0
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-04-10clk: hsdk-pll: Use managed `of_clk_add_hw_provider()`Lars-Peter Clausen1-8/+2
Use the managed `devm_of_clk_add_hw_provider()` instead of `of_clk_add_hw_provider()`. This makes sure the provider gets automatically removed on unbind and allows to completely eliminate the drivers `remove()` callback.

2023-03-29clk: hsdk-pll: Convert to platform remove callback returning voidUwe Kleine-König1-3/+2
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2017-08-31ARC: clk: introduce HSDK pll driverEugeniy Paltsev1-0/+431
HSDK board manages its clocks using various PLLs. These PLL have same dividers and corresponding control registers mapped to different addresses. So we add one common driver for such PLLs. Each PLL on HSDK board consists of three dividers: IDIV, FBDIV and ODIV. Output clock value is managed using these dividers. We add pre-defined tables with supported rate values and appropriate configurations of IDIV, FBDIV and ODIV for each value. As of today we add support for PLLs that generate clock for the HSDK arc cpus, system, ddr, AXI tunnel and hdmi. By this patch we add support for several plls (arc cpus pll and others), so we had to use two different init types: CLK_OF_DECLARE for arc cpus pll and regular probing for others plls.
