> Subject: [PATCH 1/2] clk: clk-imx8qxp: Add LPUART IPG entries > > Since commit cc7df0b9e8bc ("serial: lpuart: Enable IPG clock") the colibri- > imx8qxp board no longer boots. > > The reason is that the imx8qxp clock driver does not handle the LPUART IPG > clocks inside get_rate(), set_rate() and enable() functions. > > Fix the boot regression by adding the LPUART IPG entries. > > Fixes: cc7df0b9e8bc ("serial: lpuart: Enable IPG clock") > Reported-by: Marcel Ziswiler <marcel.ziswi...@toradex.com> > Signed-off-by: Fabio Estevam <feste...@gmail.com>
