The driver currently requires the bit clock divider be hardcoded in devicetree (or use the hardcoded default from apq8016). The bit clock divider is used to derive the baud rate from the core clock: baudrate = clk_rate / csr_div clk_rate is the actual programmed core clock rate which is returned by clk_set_rate(), and this UART driver only supports a baudrate of 115200. We can therefore determine the appropriate value for UARTDM_CSR by iterating over the possible values and finding the one where the equation above holds true for a baudrate of 115200. Implement this logic and drop the non-standard DT bindings for this driver. Tested on dragonboard410c.

This patch series adds support for ZFS listing and load to u-boot. To Enable zfs ls and load commands, modify the board specific config file with #define CONFIG_CMD_ZFS Steps to test: 1. After applying the patch, zfs specific commands can be seen in the boot loader prompt using UBOOT #help zfsload- load binary file from a ZFS file system zfsls - list files in a directory (default /) 2. To list the files in zfs pool, device or partition, execute zfsls <interface> <dev[:part]> [POOL/@/dir/file] For example: UBOOT #zfsls mmc 0:5 /rpool/@/usr/bin/ 3. To read and load a file from an ZFS formatted partition to RAM, execute zfsload <interface> <dev[:part]> [addr] [filename] [bytes] For example: UBOOT #zfsload mmc 2:2 0x30007fc0 /rpool/@/boot/uImage References : -- ZFS GRUB sources from Solaris GRUB-0.97 -- GRUB Bazaar repository Jorgen Lundman <lundman at lundman.net> 2012.
