Subject: [PATCH 0/2] Add support to Disable the flash quad mode
Date: Tue, 16 Jun 2020 21:02:25 +0800 [thread overview]
Message-ID: <1592312547-19239-1-git-send-email-yangyicong@hisilicon.com> (raw)
Previously we didn't disable the flash's quad mode when it's removed
Then comes the problem that if we next time load the flash
in SPI/Dual mode, it will not be correctly enabled as the quad enable
bits has not been cleared. I validated the condition on Cypress s25fs128s1.
This series adds the capability to disable the flash's quad mode. And
restore the flash when it's removed in spi_nor_restore().
