From e455b69ddf9b69326d0cab28d374faf3325489c9 Mon Sep 17 00:00:00 2001 From: Rui Feng Date: Wed, 29 Nov 2017 17:08:03 +0800 Subject: misc: rtsx: Move Realtek Card Reader Driver to misc Because Realtek card reader drivers are pcie and usb drivers, and they bridge mmc subsystem and memstick subsystem, they are not mfd drivers. Greg and Lee Jones had a discussion about where to put the drivers, the result is that misc is a good place for them, so I move all files to misc. If I don't move them to a right place, I can't add any patch for this driver.

00:00:00 2001 From: Rui Feng Date: Wed, 29 Nov 2017 17:09:56 +0800 Subject: misc: rtsx: Add support for RTS5260 Add support for new chip rts5260. In order to support rts5260, the definitions of some internal registers and workflow have to be modified and are different from its predecessors and OCP function is added for RTS5260. So we need this patch to ensure RTS5260 can work.

warning The pointer returned by of_device_get_match_data() doesn't have the same size as u32 on 64-bit architectures, causing a compile warning when compile-testing the driver on such platform. Cast the return value of of_device_get_match_data() to unsigned long and then to u32 to silence this warning.

For consistency purpose, the driver name for the cros_ec_dev module is now cros-ec-dev instead of cros-ec-ctl. In the next commit, the new cros_ec_dev module will be moved to the MFD subtree so mfd_add_devices() calls are not done from outside MFD.

Previously, if the 'last_transfer_ns' variable was zero, this indicated that no previous transfer had been sent and that no delay was needed. However, the EC SPI driver has been updated to always initialise the 'last_transfer_ns' variable during probe and therefore, it is no longer necessary to test if it is zero. Remove the code that checks if this variable is zero.
