From a252efadf3e7ffa8f5793cb431f35bb95bdc4795 Mon Sep 17 00:00:00 2001 From: Dmitry Osipenko Date: Sun, 23 Aug 2020 17:47:23 +0300 Subject: [PATCH] ARM: tegra: acer-a500: Set WiFi MMC clock rate to 50 MHz Previously 50MHz clock rate didn't work because of the wrong PINCTRL configuration used for SDIO pins. Now the PINCTRL config is corrected and the MMC clock rate could be bumped safely to 50MHz, increasing WiFi TX throughput by 20 Mbit/s and allowing to hit the maximum 40 Mbit/s.
