Signed-off-by: Matti Lehtimäki <matti.lehtimaki@...il.com> Signed-off-by: Luca Weiss <luca@...tu.xyz> --- To note, the cci_v1_5_data variable name is just a bit arbitrary and isn't meant to reflect IP version "1.5". I'd be happy to change the variable name to something else. drivers/i2c/busses/i2c-qcom-cci.c | 35 +++++++++++++++++++++++++++++++ 1 file changed, 35 insertions(+) diff --git a/drivers/i2c/busses/i2c-qcom-cci.c b/drivers/i2c/busses/i2c-qcom-cci.c index 5c7cc862f08f..a68f17eb9dd0 100644 --- a/drivers/i2c/busses/i2c-qcom-cci.c +++ b/drivers/i2c/busses/i2c-qcom-cci.c @@ -725,6 +725,40 @@ static const struct cci_data cci_v1_data = { }, }; +static const struct cci_data cci_v1_5_data = { + .num_masters = 2, + .queue_size = { 64, 16 }, + .quirks = { + .max_write_len = 10, + .max_read_len = 12, + }, + .cci_clk_rate = 19200000, + .params[I2C_MODE_STANDARD] = { + .thigh = 78, + .tlow = 114, + .tsu_sto = 28, + .tsu_sta = 28, + .thd_dat = 10, + .thd_sta = 77, + .tbuf = 118, + .scl_stretch_en = 0, + .trdhld = 6, + .tsp = 1 + }, + .params[I2C_MODE_FAST] = { + .thigh = 20, + .tlow = 28, + .tsu_sto = 21, + .tsu_sta = 21, + .thd_dat = 13, + .thd_sta = 18, + .tbuf = 32, + .scl_stretch_en = 0, + .trdhld = 6, + .tsp = 3 + }, +}; + static const struct cci_data cci_v2_data = { .num_masters = 2, .queue_size = { 64, 16 }, @@ -773,6 +807,7 @@ static const struct cci_data cci_v2_data = { static const struct of_device_id cci_dt_match[] = { { .compatible = "qcom,msm8916-cci", .data = &cci_v1_data}, + { .compatible = "qcom,msm8974-cci", .data = &cci_v1_5_data}, { .compatible = "qcom,msm8996-cci", .data = &cci_v2_data}, { .compatible = "qcom,sdm845-cci", .data = &cci_v2_data}, { .compatible = "qcom,sm8250-cci", .data = &cci_v2_data}, -- 2.36.0
