| | | | | | | | | | | | | | | | | | | | | | | | | | The register offset for the lcd1-ch1 clock was incorrectly pointing to the lcd0-ch1 clock. This resulted in the lcd0-ch1 clock being disabled when the clk core disables unused clocks. This then stops the simplefb HDMI output path.

|/ | | | | | | | | | | | | | | | | | | | AHB BIST gate is actually controlled with bit 7. This bug was detected while trying to use the NAND controller which is using the DMA engine to transfer data to the NAND. Since the ahb_bist_clk gate bit conflicts with the ahb_dma_clk gate bit, the core was disabling the DMA engine clock as part of its 'disable unused clks' procedure, which was causing all DMA transfers to fail after this point.

Overall it seems normal though, a few small changes to the core, mostly small non-critical fixes here and there as well as driver updates for new and existing hardware support. The biggest things are the TI clk driver rework to lay the groundwork for clkctrl support in the next merge window and the AmLogic audio/graphics clk support.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 6c0afb503937 ("clk: ti: convert to use proper register definition for all accesses") converted all register accesses in the TI clk driver to use a proper struct instead of a void pointer casted struct that fits into a u32. Unfortunately, it missed a conversion here in the didivder code, leading to a compiler warning like so: drivers/clk/ti/divider.c: In function 'ti_clk_register_divider': drivers/clk/ti/divider.c:460:8: error: 'reg' may be used uninitialized in this function [-Werror=maybe-uninitialized] Treating a 'u32' variable as a structure leads to a stack overflow here, and the register address we pass down is never initialized.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cs2000 can select Static/Dynamic ratio based Frequency Synthesizer Mode, it can select 20.12 High Multiplier interpret for 32-bit User Defined Ratio if Dynamic ratio mode. Otherwise it should select 12.20 High Accuracy mode. Current cs2000 is supporting Static ratio mode only, so it should select 12.20 High Accuracy mode, not 20.12 High Multiplier mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DEVICE_CFG2 can select ratio from user defined ratio and LOCKCLK is for it. But current driver sets fixed 0 value. This patch fixes it. Note is that current cs2000 driver is using/supporting only ratio0 (= ch0) now. DEVICE_CFG2 can select STATIC/DYNAMIC ratio mode, and current cs2000 driver is selecting STATIC mode, but it was not understandable on current code. This patch also solve this issue.

| * | clk: x86: add "mclk" alias for Baytrail/CherrytrailPierre-Louis Bossart2017-04-191-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to timing requirements, TI and Conexant manage the audio reference clock from their ASoC codec drivers using the "mclk" string. This patch adds another lookup for the "pmc_plt_clk_3" clock to avoid Intel-specific tests in those codec drivers and use code as-is. To avoid a leak, clk_add_alias() is not used in this patch. Instead the lookup is created manually as part of the .probe() step and dropped in the .remove() step. "pmc_plt_clk_3" is used exclusively for audio on all known Baytrail/CherryTrail designs and is e.g. routed on the MCLK (pin 26) of the MinnowBoardMAX Turbot LSE connector.

Current driver supports up to 2 FODs and up to 3 clock outputs. This patch sets max number of supported FODs to 4 and max number of supported clock outputs to 5.
