Date: Fri, 19 Aug 2022 11:04:43 +0800 Message-Id: <1660878283-9512-1-git-send-email-Duke.Du@quantatw.com> X-Mailer: git-send-email 2.7.4 Precedence: bulk List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Add the pmbus driver for TEXAS tps546d24 Buck Converter. The tps546d24 PMBUS_VOUT_MODE is 0x97 (i.e. the bit 5~7 are 100) which could not meet the standard pmbus spec, the standard mode of PMBUS_VOUT_MODE must be 000 (linear foramt) or 001 (vid format). Make the tps546d24 PMBUS_VOUT_MODE return value 0x17 (i.e. the bit5~7 are 000), VOUT returned value is linear11. Signed-off-by: Duke Du --- Change in v1: Initial patchset. Change in v2: Correct the tps546d24.rst format. Change in v3: 1. Modify the patch description. 2.
