From a06423c9a264d99345e1b5a04d5ced1168c609b8 Mon Sep 17 00:00:00 2001 From: Maxim Levitsky Date: Fri, 15 Oct 2010 13:06:37 -0300 Subject: [PATCH] [media] IR: ene_ir: few bugfixes This is a result of last round of debug with Sami R . Thank you Sami very much! The biggest bug I fixed is that, I was clobbering the CIRCFG register after it is setup That wasn't a good idea really And some small refactoring, etc. Tested-by: Sami R Signed-off-by: Maxim Levitsky Acked-by: Jarod Wilson Signed-off-by: Mauro Carvalho Chehab --- drivers/media/IR/ene_ir.c | 43 ++++++++++++++++++--------------------- 1 file changed, 20 insertions(+), 23 deletions(-) diff --git a/drivers/media/IR/ene_ir.c b/drivers/media/IR/ene_ir.c index 7880d9c72d47..9f9afe7c603e 100644 --- a/drivers/media/IR/ene_ir.c +++ b/drivers/media/IR/ene_ir.c @@ -156,11 +156,12 @@ static int ene_hw_detect(struct ene_device *dev) ene_notice("Firmware regs: %02x %02x", fw_reg1, fw_reg2); - dev->hw_use_gpio_0a = fw_reg2 & ENE_FW2_GP0A; - dev->hw_learning_and_tx_capable = fw_reg2 & ENE_FW2_LEARNING; - dev->hw_extra_buffer = fw_reg1 & ENE_FW1_HAS_EXTRA_BUF; - dev->hw_fan_input = dev->hw_learning_and_tx_capable && - (fw_reg2 & ENE_FW2_FAN_INPUT); + dev->hw_use_gpio_0a = !!(fw_reg2 & ENE_FW2_GP0A); + dev->hw_learning_and_tx_capable = !!(fw_reg2 & ENE_FW2_LEARNING); + dev->hw_extra_buffer = !!(fw_reg1 & ENE_FW1_HAS_EXTRA_BUF); + + if (dev->hw_learning_and_tx_capable) + dev->hw_fan_input = !!(fw_reg2 & ENE_FW2_FAN_INPUT); ene_notice("Hardware features:"); @@ -255,6 +256,8 @@ static void ene_rx_setup(struct ene_device *dev) dev->carrier_detect_enabled; int sample_period_adjust = 0; + /* This selects RLC input and clears CFG2 settings */ + ene_write_reg(dev, ENE_CIRCFG2, 0x00); /* set sample period*/ if (sample_period == ENE_DEFAULT_SAMPLE_PERIOD) @@ -268,7 +271,9 @@ static void ene_rx_setup(struct ene_device *dev) if (dev->hw_revision < ENE_HW_C) goto select_timeout; - if (learning_mode && dev->hw_learning_and_tx_capable) { + if (learning_mode) { + + WARN_ON(!dev->hw_learning_and_tx_capable); /* Enable the opposite of the normal input That means that if GPIO40 is normally used, use GPIO0A @@ -282,6 +287,7 @@ static void ene_rx_setup(struct ene_device *dev) ene_set_reg_mask(dev, ENE_CIRCFG, ENE_CIRCFG_CARR_DEMOD); /* Enable carrier detection */ + ene_write_reg(dev, ENE_CIRCAR_PULS, 0x63); ene_set_clear_reg_mask(dev, ENE_CIRCFG2, ENE_CIRCFG2_CARR_DETECT, dev->carrier_detect_enabled || debug); } else { @@ -343,19 +349,9 @@ static void ene_rx_enable(struct ene_device *dev) ene_write_reg(dev, ENE_IRQ, reg_value); } - if (dev->hw_revision >= ENE_HW_C) - ene_write_reg(dev, ENE_CIRCAR_PULS, 0x63); - - /* Enable the inputs */ - ene_write_reg(dev, ENE_CIRCFG2, 0x00); - - if (dev->rx_fan_input_inuse) { - ene_enable_cir_engine(dev, false); - ene_enable_fan_input(dev, true); - } else { - ene_enable_cir_engine(dev, true); - ene_enable_fan_input(dev, false); - } + /* Enable inputs */ + ene_enable_fan_input(dev, dev->rx_fan_input_inuse); + ene_enable_cir_engine(dev, !dev->rx_fan_input_inuse); /* ack any pending irqs - just in case */ ene_irq_status(dev); @@ -793,12 +789,10 @@ static void ene_setup_settings(struct ene_device *dev) dev->tx_period = 32; dev->tx_duty_cycle = 50; /*%*/ dev->transmitter_mask = 0x03; - - dev->learning_enabled = - (learning_mode && dev->hw_learning_and_tx_capable); + dev->learning_enabled = learning_mode; /* Set reasonable default timeout */ - dev->props->timeout = MS_TO_NS(15000); + dev->props->timeout = MS_TO_NS(150000); } /* outside interface: called on first open*/ @@ -1015,6 +1009,9 @@ static int ene_probe(struct pnp_dev *pnp_dev, const struct pnp_device_id *id) ene_warn("Simulation of TX activated"); } + if (!dev->hw_learning_and_tx_capable) + learning_mode = false; + ir_props->driver_type = RC_DRIVER_IR_RAW; ir_props->allowed_protos = IR_TYPE_ALL; ir_props->priv = dev; -- 2.20.1
