Two Factor Authentication (2FA) as been enabled for all git.whoi.edu users. For instructions on how to set up 2FA, follow the instructions on this page, or click here for a step-by-step walk-through.

Once you have 2FA setup, you may need to create an Access Token to pull and push with git. You will not be able to authenticate with git using your password once you enable 2FA. See this link for how to set up and use a Personal Access Token.

The decision to enable 2FA for all users is for added security. Oct 30th, some users experienced account lockout due to bad actors. 2FA will help prevent such incidents in the future. Thank you.

spi: spi-fsl-dspi: Use max_native_cs instead of num_chipselect to set SPI_MCR · 2c2b3ad2

Maxim Kochetkov authored Dec 01, 2020

If cs-gpios property is used in devicetree then ctlr->num_chipselect value
may be changed by spi_get_gpio_descs().
So use ctlr->max_native_cs instead of ctlr->num_chipselect to set SPI_MCR

Fixes: 4fcc7c22 (spi: spi-fsl-dspi: Don't access reserved fields in SPI_MCR)
