clk: Explicitly include correct DT includes

2023-07-19T20:13:16+00:00

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.

clk: spear: Fix SSP clock definition on SPEAr600

2022-11-23T02:03:52+00:00

There is no SPEAr600 device named "ssp-pl022.x". Instead, the description of the SSP (Synchronous Serial Port) was recently added to the Device Tree, and the device name is "xxx.spi", so we should associate the SSP gateable clock to these device names.

clk: spear: Remove uninitialized_var() usage

2020-07-16T19:32:26+00:00

Using uninitialized_var() is dangerous as it papers over real bugs[1] (or can in the future), and suppresses unrelated compiler warnings (e.g. "unused variable"). If the compiler thinks it is uninitialized, either simply initialize the variable or make compiler changes. As a precursor to removing[2] this[3] macro[4], initialize "i" to zero. The compiler warning was not a false positive, since clk_pll_set_rate()'s call to clk_pll_round_rate_index() will always fail (since "prate" is NULL), so "i" was never being initialized.

clk: spear: Make structure i2s_sclk_masks constant

2019-09-06T17:27:40+00:00

Static structure i2s_sclk_masks, having type aux_clk_masks, is only used when it is passed as the sixth argument to function clk_register_aux(). However, clk_register_aux() is defined with its sixth argument as const. Hence i2s_sclk_masks is not modified by clk_register_aux, which is also the only usage of the former. Therefore make i2s_sclk_masks constant as it is never modified. Issue found with Coccinelle.
