Subject: [PATCH v2 1/3] arm64: dts: qcom: Add PMI8996 DTSI file
Date: Thu, 27 May 2021 19:04:06 +0200 [thread overview]
Message-ID: <20210527170409.667255-1-konrad.dybcio@somainline.org> (raw)
PMI8996 is *almost* the same hardware as PMI8994, say for some annoyances:
- Boards equipped with PMI8996 now have to include pmic-id (which wasn't the case before)
- Different qpnp-ibb-discharge-resistor value (will be addressed after LABIBB is introduced)
- Different inhibit-derating-ua value (will be addressed after BCL is introduced)
- Different ramp_up_step value (will be addressed after [if?] QPNP Flash LED is introduced)
