These become a maintenance burden now, so our development group decided to remove upstream support and disable booting for this SoC. Public users only have ES2 onwards. Reviewed-by: Laurent Pinchart Reviewed-by: Niklas Söderlund Reviewed-by: Geert Uytterhoeven Signed-off-by: Wolfram Sang --- Please apply individually per subsystem. There are no dependencies and the SoC doesn't boot anymore since v6.3-rc1. drivers/thermal/rcar_gen3_thermal.c | 52 ++--------------------------- 1 file changed, 2 insertions(+), 50 deletions(-) diff --git a/drivers/thermal/rcar_gen3_thermal.c b/drivers/thermal/rcar_gen3_thermal.c index d6b5b59c5c53..e97d1798b5a3 100644 --- a/drivers/thermal/rcar_gen3_thermal.c +++ b/drivers/thermal/rcar_gen3_thermal.c @@ -14,7 +14,6 @@ #include #include #include -#include #include #include "thermal_hwmon.h" @@ -27,7 +26,6 @@ #define REG_GEN3_IRQTEMP1 0x14 #define REG_GEN3_IRQTEMP2 0x18 #define REG_GEN3_IRQTEMP3 0x1C -#define REG_GEN3_CTSR 0x20 #define REG_GEN3_THCTR 0x20 #define REG_GEN3_TEMP 0x28 #define REG_GEN3_THCODE1 0x50 @@ -46,14 +44,6 @@ #define IRQ_TEMPD2 BIT(4) #define IRQ_TEMPD3 BIT(5) -/* CTSR bits */ -#define CTSR_PONM BIT(8) -#define CTSR_AOUT BIT(7) -#define CTSR_THBGR BIT(5) -#define CTSR_VMEN BIT(4) -#define CTSR_VMST BIT(1) -#define CTSR_THSST BIT(0) - /* THCTR bits */ #define THCTR_PONM BIT(6) #define THCTR_THSST BIT(0) @@ -88,8 +78,6 @@ struct rcar_gen3_thermal_priv { struct rcar_gen3_thermal_tsc *tscs[TSC_MAX_NUM]; struct thermal_zone_device_ops ops; unsigned int num_tscs; - void (*thermal_init)(struct rcar_gen3_thermal_priv *priv, - struct rcar_gen3_thermal_tsc *tsc); int ptat[3]; }; @@ -248,11 +236,6 @@ static irqreturn_t rcar_gen3_thermal_irq(int irq, void *data) return IRQ_HANDLED; } -static const struct soc_device_attribute r8a7795es1[] = { - { .soc_id = "r8a7795", .revision = "ES1.*" }, - { /* sentinel */ } -}; - static bool rcar_gen3_thermal_read_fuses(struct rcar_gen3_thermal_priv *priv) { unsigned int i; @@ -311,34 +294,6 @@ static bool rcar_gen3_thermal_read_fuses(struct rcar_gen3_thermal_priv *priv) return true; } -static void rcar_gen3_thermal_init_r8a7795es1(struct rcar_gen3_thermal_priv *priv, - struct rcar_gen3_thermal_tsc *tsc) -{ - rcar_gen3_thermal_write(tsc, REG_GEN3_CTSR, CTSR_THBGR); - rcar_gen3_thermal_write(tsc, REG_GEN3_CTSR, 0x0); - - usleep_range(1000, 2000); - - rcar_gen3_thermal_write(tsc, REG_GEN3_CTSR, CTSR_PONM); - - rcar_gen3_thermal_write(tsc, REG_GEN3_IRQCTL, 0x3F); - rcar_gen3_thermal_write(tsc, REG_GEN3_IRQMSK, 0); - if (priv->ops.set_trips) - rcar_gen3_thermal_write(tsc, REG_GEN3_IRQEN, - IRQ_TEMPD1 | IRQ_TEMP2); - - rcar_gen3_thermal_write(tsc, REG_GEN3_CTSR, - CTSR_PONM | CTSR_AOUT | CTSR_THBGR | CTSR_VMEN); - - usleep_range(100, 200); - - rcar_gen3_thermal_write(tsc, REG_GEN3_CTSR, - CTSR_PONM | CTSR_AOUT | CTSR_THBGR | CTSR_VMEN | - CTSR_VMST | CTSR_THSST); - - usleep_range(1000, 2000); -} - static void rcar_gen3_thermal_init(struct rcar_gen3_thermal_priv *priv, struct rcar_gen3_thermal_tsc *tsc) { @@ -474,9 +429,6 @@ static int rcar_gen3_thermal_probe(struct platform_device *pdev) return -ENOMEM; priv->ops = rcar_gen3_tz_of_ops; - priv->thermal_init = rcar_gen3_thermal_init; - if (soc_device_match(r8a7795es1)) - priv->thermal_init = rcar_gen3_thermal_init_r8a7795es1; platform_set_drvdata(pdev, priv); @@ -516,7 +468,7 @@ static int rcar_gen3_thermal_probe(struct platform_device *pdev) for (i = 0; i < priv->num_tscs; i++) { struct rcar_gen3_thermal_tsc *tsc = priv->tscs[i]; - priv->thermal_init(priv, tsc); + rcar_gen3_thermal_init(priv, tsc); rcar_gen3_thermal_calc_coefs(priv, tsc, *ths_tj_1); zone = devm_thermal_of_zone_register(dev, i, tsc, &priv->ops); @@ -564,7 +516,7 @@ static int __maybe_unused rcar_gen3_thermal_resume(struct device *dev) for (i = 0; i < priv->num_tscs; i++) { struct rcar_gen3_thermal_tsc *tsc = priv->tscs[i]; - priv->thermal_init(priv, tsc); + rcar_gen3_thermal_init(priv, tsc); } return 0;
