Subject: RE: [PATCH 0/8] can: flexcan: add CAN FD support for NXP Flexcan

Hi Marc,

Kindly pinging...

After you git pull request for linux-can-next-for-5.4-20190724, some patches are missing from linux-can-next/testing.
can: flexcan: flexcan_mailbox_read() make use of flexcan_write64() to mark the mailbox as read
can: flexcan: flexcan_irq(): add support for TX mailbox in iflag1
can: flexcan: flexcan_read_reg_iflag_rx(): optimize reading
can: flexcan: introduce struct flexcan_priv::tx_mask and make use of it
can: flexcan: convert struct flexcan_priv::rx_mask{1,2} to rx_mask
can: flexcan: remove TX mailbox bit from struct flexcan_priv::rx_mask{1,2}
can: flexcan: rename struct flexcan_priv::reg_imask{1,2}_default to rx_mask{1,2}
can: flexcan: flexcan_irq(): rename variable reg_iflag -> reg_iflag_rx
can: flexcan: rename macro FLEXCAN_IFLAG_MB() -> FLEXCAN_IFLAG2_MB()

You can refer to below link for the reason of adding above patches:
https://www.spinics.net/lists/linux-can/msg00777.html
https://www.spinics.net/lists/linux-can/msg01150.html

Are you prepared to add back these patches as they are necessary for Flexcan CAN FD? And this Flexcan CAN FD patch set is based on these patches.

Thanks a lot!

Best Regards,
Joakim Zhang
