This results in missing clocks on DT-based boards like RDU1 and Babbage. Port clock tree from Linux to resolve this problem. Old non-DT clock code is kept around for the sake of the boards that were never converted to use DT. Signed-off-by: Andrey Smirnov --- Changes since [v1]: - Instead of being opt-in patch replaces i.MX51 clock code bound to "fsl,imx5*-ccm" compatible properties in DT - Code for clocks related to SPDIF and SSI were dropped [v1] http://lists.infradead.org/pipermail/barebox/2018-August/034423.html drivers/clk/imx/Makefile | 6 +- drivers/clk/imx/clk-imx5.c | 27 -- drivers/clk/imx/clk-imx51-imx53.c | 492 ++++++++++++++++++++++++++++++ 3 files changed, 495 insertions(+), 30 deletions(-) create mode 100644 drivers/clk/imx/clk-imx51-imx53.c diff --git a/drivers/clk/imx/Makefile b/drivers/clk/imx/Makefile index 8f441a97e..9d3093c96 100644 --- a/drivers/clk/imx/Makefile +++ b/drivers/clk/imx/Makefile @@ -16,9 +16,9 @@ obj-$(CONFIG_ARCH_IMX21) += clk-imx21.o obj-$(CONFIG_ARCH_IMX27) += clk-imx27.o obj-$(CONFIG_ARCH_IMX31) += clk-imx31.o obj-$(CONFIG_ARCH_IMX35) += clk-imx35.o -obj-$(CONFIG_ARCH_IMX50) += clk-imx5.o -obj-$(CONFIG_ARCH_IMX51) += clk-imx5.o -obj-$(CONFIG_ARCH_IMX53) += clk-imx5.o +obj-$(CONFIG_ARCH_IMX50) += clk-imx5.o clk-imx51-imx53.o +obj-$(CONFIG_ARCH_IMX51) += clk-imx5.o clk-imx51-imx53.o +obj-$(CONFIG_ARCH_IMX53) += clk-imx5.o clk-imx51-imx53.o obj-$(CONFIG_ARCH_IMX6) += clk-imx6.o obj-$(CONFIG_ARCH_IMX6SX) += clk-imx6sx.o obj-$(CONFIG_ARCH_IMX6SL) += clk-imx6sl.o diff --git a/drivers/clk/imx/clk-imx5.c b/drivers/clk/imx/clk-imx5.c index edebd25a3..0a5b47e29 100644 --- a/drivers/clk/imx/clk-imx5.c +++ b/drivers/clk/imx/clk-imx5.c @@ -333,18 +333,9 @@ static int imx50_ccm_probe(struct device_d *dev) return 0;
