From: Jeffrey Hugo Subject: [PATCH] arm64: dts: qcom: msm8998-mtp: Increase load on l21 for sdcard Date: Tue, 18 Dec 2018 11:04:43 -0700 Message-ID: <1545156283-5461-1-git-send-email-jhugo@codeaurora.org> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: andy.gross@linaro.org, david.brown@linaro.org Cc: robh+dt@kernel.org, mark.rutland@arm.com, bjorn.andersson@linaro.org, linux-arm-msm@vger.kernel.org, devicetree@vger.kernel.org, linux-kernel@vger.kernel.org, Jeffrey Hugo List-Id: linux-arm-msm@vger.kernel.org l21 is used as sdcard vmmc, and needs the load increased to prevent voltage drop issues with some sdcards. This addresses -84 errors seen during sdcard init with SDR104 cards.
