Subject: [PATCH v19 1/3] dt-bindings: pwm: opencores: Update compatibles, examples and maintainers
Date: Mon, 15 Jun 2026 23:57:57 +0800	[thread overview]
Message-ID: <20260615155759.129210-2-hal.feng@starfivetech.com> (raw)
In-Reply-To: <20260615155759.129210-1-hal.feng@starfivetech.com>

Remove the jh8100 compatible since the JH8100 SoC has been canceled and
will not be released. Add the jhb100 compatible to replace it.
Use a oneOf construct to support the single-string opencores,pwm-v1
compatible.

Change the register size in examples to 0x10, since an OpenCores PTC IP
has only 4 32-bit registers: CNTR, HRC, LRC and CTRL.

I will maintain this pwm module in place of William.
