regulator: bd70528: Fix off-by-one for buck123 .n_voltages setting

2021-06-23T12:42:47+00:00

[ Upstream commit 0514582a1a5b4ac1a3fd64792826d392d7ae9ddc ] The valid selectors for bd70528 bucks are 0 ~ 0xf, so the .n_voltages should be 16 (0x10). Use 0x10 to make it consistent with BD70528_LDO_VOLTS. Also remove redundant defines for BD70528_BUCK_VOLTS.

regulator: bd71828: Fix .n_voltages settings

2021-06-16T10:01:43+00:00

commit 4c668630bf8ea90a041fc69c9984486e0f56682d upstream. Current .n_voltages settings do not cover the latest 2 valid selectors, so it fails to set voltage for the hightest voltage support. The latest linear range has step_uV = 0, so it does not matter if we count the .n_voltages to maximum selector + 1 or the first selector of latest linear range + 1. To simplify calculating the n_voltages, let's just set the .n_voltages to maximum selector + 1.

mfd: da9063: Support SMBus and I2C mode

2021-05-11T12:47:31+00:00

[ Upstream commit 586478bfc9f7e16504d6f64cf18bcbdf6fd0cbc9 ] By default the PMIC DA9063 2-wire interface is SMBus compliant. This means the PMIC will automatically reset the interface when the clock signal ceases for more than the SMBus timeout of 35 ms. If the I2C driver / device is not capable of creating atomic I2C transactions, a context change can cause a ceasing of the clock signal. This can happen if for example a real-time thread is scheduled. Then the DA9063 in SMBus mode will reset the 2-wire interface. Subsequently a write message could end up in the wrong register. This could cause unpredictable system behavior. The DA9063 PMIC also supports an I2C compliant mode for the 2-wire interface. This mode does not reset the interface when the clock signal ceases. Thus the problem depicted above does not occur. This patch tests for the bus functionality "I2C_FUNC_I2C". It can reasonably be assumed that the bus cannot obey SMBus timings if this functionality is set. SMBus commands most probably are emulated in this case which is prone to the latency issue described above. This patch enables the I2C bus mode if I2C_FUNC_I2C is set or otherwise keeps the default SMBus mode.

regulator: bd718x7, bd71828, Fix dvs voltage levels

2021-03-04T10:38:07+00:00

[ Upstream commit c294554111a835598b557db789d9ad2379b512a2 ] The ROHM BD718x7 and BD71828 drivers support setting HW state specific voltages from device-tree. This is used also by various in-tree DTS files. These drivers do incorrectly try to compose bit-map using enum values. By a chance this works for first two valid levels having values 1 and 2 - but setting values for the rest of the levels do indicate capability of setting values for first levels as well. Luckily the regulators which support setting values for SUSPEND/LPSR do usually also support setting values for RUN and IDLE too - thus this has not been such a fatal issue. Fix this by defining the old enum values as bits and fixing the parsing code. This allows keeping existing IC specific drivers intact and only slightly changing the rohm-regulator.c Fixes: 21b72156ede8b ("regulator: bd718x7: Split driver to common and bd718x7 specific parts") Signed-off-by: Matti Vaittinen Acked-by: Lee Jones Link: https://lore.kernel.org/r/20210212080023.GA880728@localhost.localdomain Signed-off-by: Mark Brown Signed-off-by: Sasha Levin
