pinctrl: aspeed-g6: Make SIG_DESC_CLEAR() behave intuitively 2019-10-16T13:58:09+00:00 Andrew Jeffery andrew@aj.id.au 2019-10-08T04:41:51+00:00 c136d4c71f755a189fe13a0cd4f3e8f538dda567 Signal descriptors can represent multi-bit bitfields and so have explicit "enable" and "disable" states. However many descriptor instances only describe a single bit, and so the SIG_DESC_SET() macro is provides an abstraction for the single-bit cases: Its expansion configures the "enable" state to set the bit and "disable" to clear. SIG_DESC_CLEAR() was introduced to provide a similar single-bit abstraction for for descriptors to clear the bit of interest. However its behaviour was defined as the literal inverse of SIG_DESC_SET() - the impact is the bit of interest is set in the disable path. This behaviour isn't intuitive and doesn't align with how we want to use the macro in practice, so make it clear the bit for both the enable and disable paths.
