From bc672508592502b274e1c65038c2459654185f12 Mon Sep 17 00:00:00 2001 From: Dharma Balasubiramani Date: Tue, 5 Sep 2023 15:38:35 +0530 Subject: [PATCH] counter: microchip-tcb-capture: Fix the use of internal GCLK logic MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit commit df8fdd01c98b99d04915c04f3a5ce73f55456b7c upstream. As per the datasheet, the clock selection Bits 2:0 – TCCLKS[2:0] should be set to 0 while using the internal GCLK (TIMER_CLOCK1).
