2024-09-12soc/mediatek: Remove redundant struct pad_func and PAD_* definitionsYidi Lin
Clean up redundant `struct pad_func` and `PAD_*` definitions. This patch also refactors the PAD_* macros by, - Repurposing PAD_FUNC and dropping PAD_FUNC_SEL. - Adding PAD_FUNC_DOWN and PAD_FUNC_UP to avoid the implicit initialization.

2022-03-29mb/google/cherry: Pre-initialize PCIe at the bootblock stageJianjun Wang
Described in PCIe CEM specification sections 2.2 (PERST# Signal) and 2.2.1 (Initial Power-Up (G3 to S0)). The deassertion of PERST# should be delayed 100ms (TPVPERL) for the power and clock to become stable. Instead of asserting PERST# right before PCIe initialization and waiting for 100ms, which is currently the only function of 'mtk_pcie_pre_init', so that the extra 100ms delay in ramstage is avoided.

2021-10-02soc/mediatek: Fix I2C failures by adjusting AC timing and bus speedDaolong Zhu
1. The original algorithm for I2C speed cannot always make the timing meet I2C specification so a new algorithm is introduced to calculate the timing parameters more correctly. 2. Some I2C buses should be initialized in a different speed while the original implementation was fixed at fast mode (400Khz). So the mtk_i2c_bus_init is now also taking an extra speed parameter. There is an equivalent change in kernel side: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/i2c/busses/i2c-mt65xx.c?h=v5.15-rc3&id=be5ce0e97cc7a5c0d2da45d617b7bc567c3d3fa1 BUG=b:189899864 TEST=Test on Tomato, boot pass and timing pass at 100/300/400/500/800/1000Khz.
