From 62a094e757a75b5d0a63dfe17a7c17ab2da330fd Mon Sep 17 00:00:00 2001 From: Alex Leibovich Date: Fri, 16 Jun 2023 12:50:42 +0100 Subject: [PATCH] thermal/drivers/armada: Add support for AP807 thermal data Add support for the AP807 die thermal data. This is the same as AP806, except for the coefficients. ap807 values taken from TSENSE_ADC_16FFC spec, which says: T(in Celsius) = T(code)*TSENE_GAIN+TSENE_OFFSET where in default: TSENE_OFFSET = 128.9 TSENE_GAIN = 0.394 Signed-off-by: Alex Leibovich Tested-by: sa_ip-sw-jenkins Reviewed-by: Stefan Chulski Signed-off-by: Russell King (Oracle) Reviewed-by: Miquel Raynal Signed-off-by: Daniel Lezcano Link: https://lore.kernel.org/r/E1qA7yU-00Ea4u-Je@rmk-PC.armlinux.org.uk --- drivers/thermal/armada_thermal.c | 32 ++++++++++++++++++++++++++++++-- 1 file changed, 30 insertions(+), 2 deletions(-) diff --git a/drivers/thermal/armada_thermal.c b/drivers/thermal/armada_thermal.c index 0e8dfa6..9f6dc4f 100644 --- a/drivers/thermal/armada_thermal.c +++ b/drivers/thermal/armada_thermal.c @@ -231,7 +231,7 @@ static void armada380_init(struct platform_device *pdev, regmap_write(priv->syscon, data->syscon_control0_off, reg); } -static void armada_ap806_init(struct platform_device *pdev, +static void armada_ap80x_init(struct platform_device *pdev, struct armada_thermal_priv *priv) { struct armada_thermal_data *data = priv->data; @@ -614,7 +614,7 @@ static const struct armada_thermal_data armada380_data = { }; static const struct armada_thermal_data armada_ap806_data = { - .init = armada_ap806_init, + .init = armada_ap80x_init, .is_valid_bit = BIT(16), .temp_shift = 0, .temp_mask = 0x3ff, @@ -637,6 +637,30 @@ static const struct armada_thermal_data armada_ap806_data = { .cpu_nr = 4, }; +static const struct armada_thermal_data armada_ap807_data = { + .init = armada_ap80x_init, + .is_valid_bit = BIT(16), + .temp_shift = 0, + .temp_mask = 0x3ff, + .thresh_shift = 3, + .hyst_shift = 19, + .hyst_mask = 0x3, + .coef_b = -128900LL, + .coef_m = 394ULL, + .coef_div = 1, + .inverted = true, + .signed_sample = true, + .syscon_control0_off = 0x84, + .syscon_control1_off = 0x88, + .syscon_status_off = 0x8C, + .dfx_irq_cause_off = 0x108, + .dfx_irq_mask_off = 0x10C, + .dfx_overheat_irq = BIT(22), + .dfx_server_irq_mask_off = 0x104, + .dfx_server_irq_en = BIT(1), + .cpu_nr = 4, +}; + static const struct armada_thermal_data armada_cp110_data = { .init = armada_cp110_init, .is_valid_bit = BIT(10), @@ -681,6 +705,10 @@ static const struct of_device_id armada_thermal_id_table[] = { .data = &armada_ap806_data, }, { + .compatible = "marvell,armada-ap807-thermal", + .data = &armada_ap807_data, + }, + { .compatible = "marvell,armada-cp110-thermal", .data = &armada_cp110_data, }, -- 2.7.4
