From 6f6878ec6faf16a5f36761c93da6ea9cf09adb33 Mon Sep 17 00:00:00 2001 From: Ondrej Jirman Date: Mon, 19 Jun 2023 03:09:58 +0200 Subject: soc: rockchip: grf: Fix SDMMC not working on RK3588 with bus-width > 1 RK3588 has the same issue as other earlier RK SoCs. JTAG functionality muxed to some SDMMC data pins causes issues with SDMMC interface. Without this patch, I can only use SDMMC inteface with bus-width = <1>. (JTAG is muxed to data pins D2 and D3) Signed-off-by: Ondrej Jirman Link: https://lore.kernel.org/r/20230619011002.2249960-1-megi@xff.cz Signed-off-by: Heiko Stuebner --- drivers/soc/rockchip/grf.c | 14 ++++++++++++++ 1 file changed, 14 insertions(+) (limited to 'drivers/soc') diff --git a/drivers/soc/rockchip/grf.c b/drivers/soc/rockchip/grf.c index 15a3970e3509..d768c5a70174 100644 --- a/drivers/soc/rockchip/grf.c +++ b/drivers/soc/rockchip/grf.c @@ -121,6 +121,17 @@ static const struct rockchip_grf_info rk3566_pipegrf __initconst = { .num_values = ARRAY_SIZE(rk3566_defaults), }; +#define RK3588_GRF_SOC_CON6 0x0318 + +static const struct rockchip_grf_value rk3588_defaults[] __initconst = { + { "jtag switching", RK3588_GRF_SOC_CON6, HIWORD_UPDATE(0, 1, 14) }, +}; + +static const struct rockchip_grf_info rk3588_sysgrf __initconst = { + .values = rk3588_defaults, + .num_values = ARRAY_SIZE(rk3588_defaults), +}; + static const struct of_device_id rockchip_grf_dt_match[] __initconst = { { @@ -147,6 +158,9 @@ static const struct of_device_id rockchip_grf_dt_match[] __initconst = { }, { .compatible = "rockchip,rk3566-pipe-grf", .data = (void *)&rk3566_pipegrf, + }, { + .compatible = "rockchip,rk3588-sys-grf", + .data = (void *)&rk3588_sysgrf, }, { /* sentinel */ }, }; -- cgit v1.2.3
