2018-12-07mtd: rawnand: denali: remove denali_reset_banks()Masahiro Yamada1-29/+0
In nand_scan_ident(), the controller driver resets every NAND chip. This is done by sending NAND_CMD_RESET. The Denali IP provides another way to do the equivalent thing; if a bit is set in the DEVICE_RESET register, the controller sends the RESET command to the corresponding device. denali_reset_banks() uses it to reset all devices beforehand. This redundant reset sequence was needed to know the actual number of chips before calling nand_scan_ident(); if DEVICE_RESET fails, there is no chip in that chip select. Then, denali_reset_banks() sets denali->max_banks to the number of detected chips. As commit f486287d2372 ("mtd: nand: denali: fix bank reset function to detect the number of chips") explained, nand_scan_ident() issued Set Features (0xEF) command to all CS lines, some of which may not be connected with a chip. Then, the driver would wait for R/B# response, which never happens. This problem was solved by commit 107b7d6a7ad4 ("mtd: rawnand: avoid setting again the timings to mode 0 after a reset"). In the current code, nand_setup_data_interface() is called from nand_scan_tail(), which is invoked after the chip detection. Now, we can really remove the redundant denali_nand_banks() by simply passing the maximum number of chip selects supported by this IP (typically 4 or 8) to nand_scan(). Let's leave all the chip detection process to nand_scan_ident(). Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>
2018-12-07mtd: rawnand: denali: remove ->dev_ready() hookMasahiro Yamada1-22/+1
The Denali NAND IP has no way to read out the current signal level of the R/B# pin. Instead, denali_dev_ready() checks if the R/B# transition has already happened. (The INTR__INT_ACT interrupt is asserted at the rising edge of the R/B# pin.) It is not a correct way to implement the ->dev_ready() hook. In fact, it has a drawback; in the nand_scan_ident phase, the chip detection iterates over maxchips until it fails to find a homogeneous chip. For the last loop, nand_reset() fails if no chip is there. If ->dev_ready hook exists, nand_command(_lp) calls nand_wait_ready() after NAND_CMD_RESET. However, we know denali_dev_ready() never returns 1 unless there exists a chip that toggles R/B# in that chip select. Then, nand_wait_ready() just ends up with wasting 400 msec, in the end, shows the "timeout while waiting for chip to become ready" warning. Let's remove the mis-implemented dev_ready hook, and fallback to sending the NAND_CMD_STATUS and nand_wait_status_ready(), which bails out more quickly.

2018-12-07mtd: rawnand: ams-delta: Request data port GPIO resourceJanusz Krzysztofik1-2/+9
Data port used by the driver is actually an OMAP MPUIO device, already under control of gpio-omap driver. For that reason we used to not request the memory region of the port as that would fail because the region is already busy. Despite that, we are still accessing the port by just ioremapping it and performing read/write operations. Moreover, we are doing that without any proteciton from other users legally manipulating the port pins over GPIO API. The plan is to convert the driver to access the port over GPIO consumer API. Before that happens, already prevent from other users accessing the port pins by requesting an array of its GPIO descriptors.
