-Subject: serial: sc16is7xx: add check for unsupported SPI modes during probe
-
-From: Hugo Villeneuve <hvilleneuve@dimonoff.com>
-
-commit 6d710b769c1f5f0d55c9ad9bb49b7dce009ec103 upstream.
-
-The original comment is confusing because it implies that variants other
-than the SC16IS762 supports other SPI modes beside SPI_MODE_0.
-
-Extract from datasheet:
- The SC16IS762 differs from the SC16IS752 in that it supports SPI clock
- speeds up to 15 Mbit/s instead of the 4 Mbit/s supported by the
- SC16IS752... In all other aspects, the SC16IS762 is functionally and
- electrically the same as the SC16IS752.
-
-The same is also true of the SC16IS760 variant versus the SC16IS740 and
-SC16IS750 variants.
-
-For all variants, only SPI mode 0 is supported.
-
-Change comment and abort probing if the specified SPI mode is not
-SPI_MODE_0.
-
-Fixes: 2c837a8a8f9f ("sc16is7xx: spi interface is added")

-Subject: serial: sc16is7xx: set safe default SPI clock frequency
-
-From: Hugo Villeneuve <hvilleneuve@dimonoff.com>
-
-commit 3ef79cd1412236d884ab0c46b4d1921380807b48 upstream.
-
-15 MHz is supported only by 76x variants.
-
-If the SPI clock frequency is not specified, use a safe default clock value
-of 4 MHz that is supported by all variants.
-
-Also use HZ_PER_MHZ macro to improve readability.
