Like how pci.c exposes hif ops for the bus specific operation, expose similar hif ops table for ahb with all required functions linked to it. Many ath10k_pci_* functions are reused here in hif ops table. If something is not sharable, new functions are added for ahb and linked to hif ops table. Finally, make ath10k_ahb_probe/remove() to perform what is expected out of it. Signed-off-by: Raja Mani <rmani@qti.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
