Message-Id: <20220825150224.826258-6-msp@baylibre.com> X-Mailer: git-send-email 2.37.2 In-Reply-To: <20220825150224.826258-1-msp@baylibre.com> References: <20220825150224.826258-1-msp@baylibre.com> MIME-Version: 1.0 Precedence: bulk List-ID: X-Mailing-List: linux-omap@vger.kernel.org TPS65219 has different interrupts compared to other TPS6521* chips. TPS65219 defines two interrupts for the powerbutton one for push and one for release. This driver is very simple in that it maps the push interrupt to a key input and the release interrupt to a key release.
