Subject: [PATCH 1/1] spi: dt-bindings: amlogic, meson-gx-spicc: Fix schema for meson-g12a
Date: Tue,  9 Jun 2020 18:55:27 +0200
Message-ID: <20200609165527.55183-1-alexander.stein@mailbox.org> (raw)

This fixes the following warning during dtbs_check:
---
spi@13000: clock-names: Additional items are not allowed ('pclk' was unexpected)
spi@13000: clock-names: ['core', 'pclk'] is too long
spi@13000: clocks: [[2, 23], [2, 258]] is too long
spi@15000: clock-names: Additional items are not allowed ('pclk' was unexpected)
spi@15000: clock-names: ['core', 'pclk'] is too long
spi@15000: clocks: [[2, 29], [2, 261]] is too long
---
Conditional schema properties don't overwrite others. Instead of
restrictions have to be validated. So general clock amount is 1-2 and
depending on the actual device type limit the mount to 1 or 2.
