clk: imx: clk-imx8qxp: Register DC0 display clocks with imx_clk_scu2() This patch corrects display clocks for i.MX8qxp DC0 subsystem by calling imx_clk_scu2() to register them, instead of calling imx_clk_scu(). The reason is that the clocks can source from various parents. The clock source selection is controlled by Distributed Slave System Controller(DSC). According to the DSC spec, the below table describes the generic source selections for clocks with the same type in various subsystems. And, the display controller subsystem spec says the display clocks can source from PLL1, PLL2 or bypass clock, thus we may specify the correct parents for imx_clk_scu2(). The bypass clock's parent is determined by the SCU firmware. Currently, the parent is 'pixel_link_clk_in' from HW point of view. To be more specific, the parent is dummy for i.MX8qxp DC0, while HDMI TX PHY PLL for i.MX8qm DC0. In practice, the display clocks source from the bypass clock only when driving i.MX8qm HDMI TX. So, for the both display clocks, we simply specify 'dc0_bypass0_clk' bypass clock as a valid parent. ----------------------------------------- | src_sel[28:26] | | ----------------------------------------- | 0x0 | xtal24M | | 0x1 | PLL0 | | 0x2 | PLL1 | | 0x3 | PLL2 | | 0x4 | bypass reference clock | | 0x5 to 0x7 | reserved | ----------------------------------------- Cc: Michael Turquette <mturquette@baylibre.com> Cc: Stephen Boyd <sboyd@kernel.org> Cc: Shawn Guo <shawnguo@kernel.org> Cc: Sascha Hauer <s.hauer@pengutronix.de> Cc: Pengutronix Kernel Team <kernel@pengutronix.de> Cc: Fabio Estevam <festevam@gmail.com> Cc: NXP Linux Team <linux-imx@nxp.com> Cc: Dong Aisheng <aisheng.dong@nxp.com> Signed-off-by: Liu Ying <victor.liu@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

clk: imx: scu: add two cells binding support This patch implements the new two cells binding for SCU clocks. The usage is as follows: clocks = <&uart0_clk IMX_SC_R_UART_0 IMX_SC_PM_CLK_PER> Due to each SCU clock is associated with a power domain, without power on the domain, the SCU clock can't work. So we create platform devices for each domain clock respectively and manually attach the required domain before register the clock devices, then we can register clocks in the clock platform driver accordingly. Note because we do not have power domain info in device tree and the SCU resource ID is the same for power domain and clock, so we use resource ID to find power domains. Later, we will also use this clock platform driver to support suspend/resume and runtime pm.

clk: imx8qxp: add clock valid checking mechnism clk-imx8qxp is a common SCU clock driver used by both QM and QXP platforms. The clock numbers vary a bit between those two platforms. This patch introduces a mechanism to only register the valid clocks for one platform by checking the clk resource id table.
