Date: Fri, 24 Feb 2023 12:38:35 +0100 Message-Id: <20230224113837.874264-1-jneanne@baylibre.com> X-Mailer: git-send-email 2.34.1 MIME-Version: 1.0 Precedence: bulk List-ID: X-Mailing-List: linux-omap@vger.kernel.org GPIO interface consist in 3 pins: Two GPIOS are output only: GPO1, GPO2. GPIO0 is used for multi device support: - The input-functionality is only used in multi-PMIC configuration - In single-PMIC, it can be used as an output The configuration is static and flashed in NVM in factory. Description tps65219.pdf chapter 7.3.13 Linux must not change MULTI_DEVICE_ENABLE bit at run time. This was done for test purpose only to check input/output correct behavior on EVM board (no access to different NVM config). Tested on k3-am62x-lp-sk board. This board MULTI_DEVICE_ENABLE=0 Despite the register bits are out of order, driver is remapping in natural order: GPIO0 is gpiochip line 0 GPO1/2 are gpiochip line 1/2 Initial version by Jon Cormier on TI Mainline.
