phy: mediatek: mipi: mt8183: fix minimal supported frequency

2024-01-10T16:16:57+00:00

[ Upstream commit 06f76e464ac81c6915430b7155769ea4ef16efe4 ] The lowest supported clock frequency of the PHY is 125MHz (see also mtk_mipi_tx_pll_enable()), but the clamping in .round_rate() has the wrong minimal value, which will make the .enable() op return -EINVAL on low frequencies. Fix the minimal clamping value.

phy: Explicitly include correct DT includes

2023-07-17T06:22:56+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.

All of the entries do fit in a maximum of 82 columns, which is acceptable. While at it, also remove the useless comma on the last entry and add the usual sentinel comment.

phy: mediatek: mipi-dsi: Use devm variant for of_clk_add_hw_provider()

2023-07-12T16:57:42+00:00

Switch to devm_of_clk_add_hw_provider() in the probe function: this also allows to entirely remove the .remove_new() callback, as its only task was to unregister the clock provider.

phy: mediatek: mipi-dsi: Convert to register clk_hw

2023-07-12T16:57:42+00:00

Instead of registering a struct clk, directly register clk_hw: this allows us to cleanup a pointer to struct clk from struct mtk_mipi_tx.
